Every film must be judged on its own merit. Even if CITIZEN KANE is a 5 star film (whatever grading scale), it’s 5 stars on its own merit. The scale must be applied within the confines of what the film is trying to do and does it succeed and was it bad, good or great. Just my opinion.
SW77 - ***** stars
TESB - ***** stars
ROTJ - **** stars
TPM - ** stars
AOTC - * star
ROTS - *** stars
TFA - ****½ stars
Nice. I like to rate films on their own scales too. Most don’t, but that way makes more sense to me.
